ONG FUI? SHORT/CUI? .CETHTE INVENTOR y @4f/@iwal ATTORNEYSlnatentedzli'eb. 18,- 1947 YARN" Austin N. Oppenheim. New York, N. Y.,mimm-V to Unique Fibers, Inc., New York, N. Y., a oorporation of NewYork Appucauon Much 12,1946, sensiNo. 653,965 l This invention relatesto yarns made of a, mixture or blend. of fibres -of different kinds andis concerned more particularly with a novel yarn which may be employedin the production of fabrics of unusual and attractive appearance andremarkable softness in hand 'and drape. The new yarn can bef'produced atrelatively lowcost for preparing and spinning operations and may be usedinthe manufacture of woven and knitted fabrics without changes in themachines or methods ordinarily employed.

The yarn of the invention includes a substantial proportion of animalfur, which may be either the fur or hair ,of animals, or a mixture ofboth fur and hair. Preferably, .theyarn includes a mixture of furs ofdifferent characteristics, so

' that the fur content of the yarn may give softness, lustre,springiness, novel surface effects,

etc., to fabrics made of the yarn. In addition, the yarnincludes amixture of synthetic fibres, which act as a carrier, provide body, givetheyarn soft ness and smoothness, and also bind in the fur fibres. AInmy co-pending application, Seria1 No. 558,- 1.64,5 mea october '12,1944, I disclosed a yam spun from a .blended mixture of syntheticfibres, wool, and fur, and pointed out that the wool performed thefunction of binding in the other-` flbres and strengthening the yarn andalso that the wool content gave fullness, spring, and resilience tofabrics made of the yarn. While the yarn of the co-pending applicationhas proven highly satisfactory for many purposes, instances occur inwhich the presence of the wool is ob jectionable, because of theparticular use to'k which fabrics made `of the yarn are to be put. InmyA further experiments with the prior yarn, I have found that a yarnsimilar in its general char.

found to serve many lof the useful purposes served by the wool in theprior yarn, particularly the binding' function, and the new yarn may,accordingly, be employed in the production of various fabrics in whichthe. presence `of the fur content is desired but the use of wool is tobe avoided.'

In making they new `various kinds and find that mink, muskrat, wolf,squirrel, fox, beaver, ermine, nutria, opossum,

sable, seal, and raccoon are most desirable. These furs differ widely intheir physical characteristics and, for that reason, I prefer to usecombinations of two or more different kinds of fur to obtain noveleffects. For example, mink and muskrat fur may be used to advantage,`because mink is -amounts varying from about 10%. to about 65%,

acteristics to the prior yarn and entirely satisfactory in respect towearing qualities and freedom from shedding ofthe fur fibres used, maybe made by a proper selection of the constituents of the synthetic fibrecontent of the blended mixture to be spun. Y

The single gure 4of the drawing is a view in perspective of one form ofthe new yarn.

In the new yam, I employ with the fur a soft and. lustrous and givesdesirable surface effects while muskrat imparts spring to the fabric.Another combination that may be used consists of opossumlwhichV is arelatively long soft fur, and muskrat. Other desirable combinations arewolf and muskrat. fox, squirrel, and muskrat. and fox. and muskrat. Ingeneral, it may be said that the short furs mainly providecharacteristics I' of handle, drape, etc.. to fabrics made of the yarn,

while the longfurs primarily give surface effectsand provide coverage.

The blend of fibres of which the new yarn spun is composed of vfibres ofsynthetic materials.

exclusive ofA organic derivatives of cellulose, in

amounts varying from about 10% to about 85%.

fibres of .organic derivatives of cellulose in andfurin amounts varyingfrom about 10% to 50%. Al specific example of the new yarn that issatisfactory for many purposes consists essentially of about 60% viscoserayon fibres, about 20% "cellulose acetate fibres, and about 20%` fur,while another form of the new yyarn consists essentially of about 50%viscose rayon fibres', about 25% cellulose acetate fibres, and ,about.20% fur. In these particular yarnsthe'fur content preferably includestwo or more different kinds of fur,

mixture of synthetic fibres, which may include any of such fibresexclusive of those of organic derivatives of cellulose, that arecommonly employed in yarn manufacture, vtogether with a substantialproportion of fibres made of organic derivatives of cellulose. Whensucha mixture of synthetic fibres is mixed with fur and spun, the fibres ofthe `organic derivatives of cellulose are v proportions may be made inorder to meet ecothe kinds of fur being selected inwview of thecharacteristics which the yarn is to have and the nature and intendeduse of the` fabrics into which itis to be woven or knitted.

` The 'proportions of the constituent bres of I I the yarn will vary inaccordance withl the characteristics, suh as drape. hand,richness,sofi;-` ness, and appearance, thatfthe fabricsl made therefrom-are to have. Also,` variations in the nomic conditions.

The example of new yarn illustrated in the yarn, I -use animal fur of i-aaiaaoo drawing contains libres of rayon. for example,- viscose rayon,acetate fibres. .relatively short i'ur fibres, such as mink, and longerfur libres, such as muskrat,

i In the production' of the new yarn. the blended mixture of the'constituents is preferably spun on derivatives of cellulose, inan'anount varying from about 10% to about 80%. flbresoforganicderivatives of cellulose in an amount varying the cotton system,because of the lower cost and A greater ease of. manufacture, and thestaple lengths of the synthetic bres used will be chosen with that endin view. Many of the fur fibres are naturally of a staple length whichpermits them to be handled on the cotton system, but,

for that purpose, theilbres may be readily shortened. It is to beunderstood that the new yarn j can also be produced on the woolensystem,in which event, fibres of llonger staple length may be employed,although the cost ot production of the yarn is likely to be increased.

The new yarn may be made as either a singles yarn or vas "a plied yarn.`It will vary in count according toI the type of fabric in which it isto be used and the twist will vary in the same way and also inaccordance with lwhether it is to bel used in weaving or knittingoperations.
